What did the PDP-11 do?

PDP-11/45 (1972), PDP-11/50 (1975), and PDP-11/55 (1976) – A much faster microprogrammed processor that can use up to 256 kB of semiconductor memory instead of or in addition to core memory; support memory mapping and protection.

Who improved the C programming language?

Dennis M. Ritchie
C, computer programming language developed in the early 1970s by American computer scientist Dennis M. Ritchie at Bell Laboratories (formerly AT Bell Laboratories).

How the C language was developed?

The origin of C is closely tied to the development of the Unix operating system, originally implemented in assembly language on a PDP-7 by Dennis Ritchie and Ken Thompson, incorporating several ideas from colleagues. Eventually, they decided to port the operating system to a PDP-11.

Which operating system was developed using the programming language C?

UNIX
Explanation: C programming language is invented for developing an operating system called UNIX. By 1973, the complete UNIX OS is developed using C.

What is PDP in architecture?

About PDP Architects — Preservation Design Partnership.

What is PDP computer fundamentals?

Programmed Data Processor (PDP), referred to by some customers, media and authors as “Programmable Data Processor,” is a term used by the Digital Equipment Corporation from 1957 to 1990 for several lines of minicomputers.

When and where did C programming language evolve?

The Beginning The C programming language came out of Bell Labs in the early 1970s. According to the Bell Labs paper The Development of the C Language by Dennis Ritchie, “The C programming language was devised in the early 1970s as a system implementation language for the nascent Unix operating system.

How many physical 4 byte words are there on a PDP-11?

The PDP-11/70 uses 22 bits for addressing physical memory. This represents a total of 222 (over 4 million) byte locations. Of the over 4 million byte locations possible with the 22-bit address, the top 256K are used to reference the UNIBUS rather than physical memory.
